glycoproteins

“Glyco” means “sugar”, so glycoproteins are a type of protein linked to a sugar. They’re considered a type of peptide and are naturally present in skin’s surface as well as throughout the body.

On skin, glycoproteins work with ingredients like glycerin, ceramides, and hyaluronic acids to keep skin intact, smooth, and healthy-looking. They can also enhance skin’s natural resilience by reinforcing skin barrier strength.

Glycoproteins help other peptides be more soluble in water and within skin, so some products add them along with specific peptides as a way to enhance delivery and stability of the formula.
